Appuminseptember' 11,1935, seria1No.4o,osz A9 claims. (ci. 29e- 164) Thisinvention relates to improvements in locks for doors and particularly tolocks for securing the doors-of motor vehicles.

In my Patent No. 1,908,343, granted May 9,

1932, is disclosed a lock and latch which comprises essentially awedging means adapted to be secured to a door and a'wedge receivingAmeans adapted to be secured to a door frame, the wedge or near thecenter` of the door. As is Well-known,

the operating handle of the remote control devices customarily employedfor the operation of motor vehicle locks may be moved in either of twodirections, movement in one direction effecting retraction of the latchbolt and thus releasing the door and movement in the other directioneiecting the locking of the latch bolt so that the lock may not bereleased or operated by anyone without the vehicle. Without additionalmeans it is possible for the operator of a motor vehicle of the closedbody type to so adjust the locks of the vehicle doors that, after theoperator has moved to the outside of the vehicle and closed the doorsthereof, he cannot thereafter open them, being eiectively locked out.

Hence it is customary for manufacturers of such vehicles to providemechanism in addition to the ordinary latch and remote control mechanismfor preventing the operator from locking himself out of the vehicle by acertain procedure in manipulating the remote control handles, which inturn operates the inside locking device; for example, if the operator ofa four door sedan body, after completely locking the car from theinside, chooses to exit from the left front door, and after leaving thevehicle and While the door is still openlocls the door by reversing theremote control handles and then slams the door" tains the outside lock,and lock the vehicle with the key. It is customary in this country toprovideK the outside key lock on the right side of the vehicle next tothe curb when parking, and the steering wheel on the left side of thevehicle, while in certain countries this practice is reversed,-therefore necessitating the rev'ersal of the procedure of Ilocking.

The present invention contemplates the addition to and combination withthe novel form of lock and latch disclosed in myprior patent of amechanism of the type just referred to. That is, a mechanism which makesit impossible for a vehicle operator to lock the door to which -thevmechanism is applied by operating the inside locking device save withthe door in completely closed position. The invention contemplates the`combination with the wedging means which is to be applied to a door ofa device which cooperates with the moving parts of the lock in suchmanner as to insure that these parts may not be set by the operatorprior to his leaving the vehicle in such manner as to automatically lockhim out when the door is closed after his exit therefrom.

Numerous ways of eiecting the desired objects may be devised and in theaccompanying drawings several mechanisms of this character are`illustrated by Way of example.'

Numerous parts of the lock supporting frame and certain of its operatingmembers may be of conventional form and need not be described in greatdetail. A complete locking unit, however, will comprise a wedging meansand its associated parts, such as illustrated in the first ten figuresof the drawings, which means is adapted to be mounted upon adoor, andthe `wedge receiving means illustrated in Figures. 12 and 13, which isadapted to be mounted upon the ,door frame. 'Conceivably, in certaininstances the wedge receiving meansv may be. `mounted upon the doorandthe wedging means Vupon the door frame, as will be understood. butpreferably the wedging means', which includes the latch bolt, will bemounted upon the door and the wedge receiving means upon the door frame.

Referring now to the preferred form of the invention shown in Figures 1to 13 inclusive. The wedging means previously referred to comprisesessentially a supporting arm or lug II) which' is adapted to projectbeyond the free edge of the door for a comparatively short distance asshown in Figure 1 in which the approximate position of the free edge ofthe door is indicated by the chain line a-a. The flat upper surfac`e ofarm I is preferably substantially horizontal in the case of vehicledoors or at any rate is disposed substantially normally to the axisabout which the door swings inl its opening and closing movements. Incross-section, member I0 is itself slightly wedge shaped, as shown inFigures and 6 with its thinner .edge rounded as shown. The wedging meansincludes not only themember I0 but also the latch bolt II, this bolthaving a flat lower surface which slidably rests upon and is supportedby, the nat upper surface of the supporting arm I0. The latch boltportion II of the wedging means is likewise itself wedge shaped incross-section, its thinner or leading edge being rounded as shown.Intermediate its edges the latch bolt is provided on its upper surfacewith a tooth I2, which tooth will perform latching functions when thedoor is only partially closed.

The wedge receiving means includes a suitable casing orhousing memberI3, the details of which may vary within wide limits, and which isadapted to be firmly secured to a door frame member and to serve as ahousing and support for the operating parts of the wedge receivingmeans. This wedge receiving means includes spaced metallic wedgecontacting members I4 and I5 and backing and supporting blocks I6 and I1of rubber, these blocks serving to resiliently support, againstseparation, the jaws I4 and I5. The upper surface of the lower metallicjaw member I5 is inclined as shown in Figure 5 and is a smooth surfacein order that it may have full contact with the inclined lower surfaceof supporting arm I0 when the door is closed, as indicated in thisfigure. The lower surface of the upper jaw I4 of the wedging means istoothed orl serrated, the intermediate tooth I8 thereof being adapted todrop down behind tooth I2 of the wedging means when the door I iscompletely closed and the enlarged tooth I9 Figure 5 vduring the flnalclosing movement of the door, the rubber blocks i6 and II respectivelybeing compressed as the upper and lower jaws I4 and I5 are parted toreceive the wedging means and thereafter expanded to maintain the jawsI4 and I5 in tight engagement with the wedging means. Any portion of theweight of the door which may not be carriedby the hinges, due tolooseness and wear, will be transmitted to the jaw I5 and thence throughthe rubber block I'I to the door frame so that it is apparent that atall times while the door is shut it is resiliently supported at its freeedge by the wedge receiving means, thus taking a portion of the weight.of the door off the hinges if the wedge receiving means is properlypositioned, vand preventing rattling due to vertical movementsv of thedoor or to vibrations of the vehicle to which it isr attached, the upperexpansible rubber block I6 pressing the upper jaw I4 downwardly at alltimes into close engagement with theupper surface of the latch bolt. Inthe event that the door is only partially closed, the shoulder I2 vofthe latch bolt will engage in behind the tooth I9 of the upper jaw I4and the door will be retained in this position, effectively lockedagainst outward swinging, until the. operator has opportunity to effectthe complete closure thereof.

To permit opening the door, the latch bolt portion II of the wedgingmeans is axially'retracted, causing its upper surface to disengage thelower surface of the-upper jaw I4 of the wedge receiving means andthereafter the door may be freely swung open. 'I'he various parts thusfar described are, in essence, described and claimed in my prior patentabove referred to.

As will be observed upon an inspection of Figure 5, the rubber blocks I6and I'I do not solidly ll the housings or casings Within which they arecontained but the outer ends are cut away at I6 and I1 and slightrecesses |62 and i12 also formed therein. This causes the outer ends ofthe cushioning blocks to be more freely yieldable than the remainingportions and facilitates the closing movement of the door by permittingthe wedging means, i. e., the arm I0 and latch bolt I I, to more easilypass the depending tooth I9.

The 'base or supporting plate upon which the operating parts of the lockare mounted is indicated generally at 20 and this plate is ofconventional form, the main portion thereof being adapted to lieparallel to the plane of the door and an integral part 2l, disposed atapproximately right angles to the main portion, being adapted to lieflush with the edge surface of the door. The supporting arm or lug I0projects through an opening formed in part 2I` of the plate 20 and adownwardly extending portion I0' thereof is firmly secured to plate 2Dby means of rivets 22 so that, base plate 20 being rigidly secured tothedoor, the supporting arm I is hat.

rigid with the door.

The latch bolt member Il vof vthe wedging vmeans likewise projectsthrough the aperture formed in the face plate 2i and its inner end isattached to the member 23, as shown ln several i'lgures of the drawings.Member 23 may be slidably mounted upon the supporting or base plate 22in any conventional manner, has the somewhat irregular shape shown inthe drawings, and is disposed in a. generally vertical plane parallel tothe plate 22. The enlarged end of member 22 adjacent latch bolt li isslightly raised with respect to the remainder of the member and isdisposed in a plane parallel to th remainder thereof (as viewed inFigure 1) but the member as a wholemay be described as being generallyMember 22, and hence the latch bolt, is operated when the slide 2t islongitudinally reciprocated, from the position in' which" it is shown inFigures 1 and d, to the position in which it is shown in Figure 9, thelatch bolt being shown as fully retracted in this last mentioned figure,a lug 25 projecting laterally from member 23 lying in the path ofmovement of a shoulder 26 of slide 2t' so that member 23 and slide 22move simulslide 2t is released, therefore, both member 23 y and theslide are moved forwardlyor to the left (Figure l) by reason oi' theaction of the spring 2i, and this movement continues until the latch-bolt is fully projected and occupies the position in which it is shownin Figures 1 and 4.

Retraction of the slide 2li'. in the manner just described may beedect'ed by means ofthedistant control, parts of which are shown inFigure l. A specific description of a distant control need not be given,inasmuch as it may be of conventional type, it being suiiicient forpresent purposes to state that the lever 32 oi this mechanism may v bemanually operated to eiiect retraction of a slide 22,` through theintermediary ofthe linlr 2i, which is pivotally connected both to lever22 and slide 2d. Normally the lever 32 occupies the positions in whichit is shown-in full lines in Figure l. When the latch bolt is to beretracted by means of the distant control, the lever .itil is moved tothe position in which it is shown .in dotted lines in Figure 1 andindicated at A. When the distant control is to be actuated to bringabout setting of the lock so that it may not be opened from without thevehicle by the manipulation ofv the customary handle, it is moved todotted line position B, thus thrusting outwardly or to theleft (Figure3) the slide 24 and thereby bringing the locking lug 32 of this slideinto position to prevent rotation' of the door operating handle fromwithout, as will be hereinafter more particularly described. Slide 24also includes an outwardly projecting portion 33 the` function of whichwill 'be hereinafter fully described.

Not only may the member 23 be operated by the distant control to eiectretraction of the latch bolt but it may likewise be retracted or thrustto the right (Figure 4) by the camming member 34 Yshown in Figure l.

end of member 23 when rotated in a clockwise direction (Figure 4) totherefore thrust member v:al

23 to the right and eilect retraction of the latch bolt. When cammingmember 34 is released it is returned automatically to the position inwhich it is shown in Figure 4 by the action of' 'spring 2l.. When slide24 is moved by means of operating lever 32 and link 2i to the positionin which it is shown in Figure 8, the locking lug 22 of this slideprojects into the angle between arms 242 and 223, arid in this way thecamming member is locked against rotation in either direction by the'slide.

Likewise the comming member 24 may be locked against rotation in eitherdirection by a locking device which includes the vertically slidablemember 22 and the cam 2i which may be 'manipulated from without thevehicle, as by means of a keyto raise slide 2t from the position inwhich it is shown in Figure d to the position4V in which its upper end32' lies in the path of movement of the arm 243 of the cammina member2t, thus preventing rotation oi the camming member and retractivemovement of the latch bolt. To make itnecessary for the operator of thevehicle, in eiiecting the vehicle locking thereof, to use the hey fromthe outside, it is necessary to provide means for rendering the distantcontrol mechanism ineective to accomplish locking of the camming member2t by preventing movement of thel distant control operated slide 24 intosuch position that the locking lug 32 thereof moves to the ,position inwhich it is shown in Figure 8 when the door is open.

This means includes a sliding frame, generally indicated at i2-having avertically extending body portion di slidably mountedV upon verticallyextending prongs t2 integral ywith the face plate 2i and normallymaintained inthe position in which it is shownin Figure l0, by means ofa compression spring t3, the upper end of which .bears against thesliding frame and the lower end of which rests upon an inwardlyprojecting lug Mi integral with the face plate 2i. Sliding frame tid hasa slide obstructing arm tt which normally lies in the plane of slide 2dand directly in the path of movement of the forwardly projecting portion22A oi the slide, as Hence it is apparent that the distant control maynot be so operated as to move vslide 2t into the position in which it isshown in Figure 8, so long as the sliding frame Mi occupies its normalposition, thus making it impossible for a person to lock the cammingmember 32 against movement until the obstructing arm fit is lowered fromthe position in which f vided with a second arm 45 positioned 'closelyadjacent the relative face of the wedging means comprising lug i0 andlatch bolt il an-d normally lying immediately in rear of the latch bolt,as indicated in Figure 10. When the door is slammed and the wedging andwedge receiving means come into full engagement, as shown in Figure 5,the arm 45 of the sliding frame will be engaged by the tooth I9 as fullwedging engagement of the parts is realized andwill be moved downwardly,carrying the entire frame 40 with it, the arm 45 being moved to theposition in which it is shown in Figure 5 and` arm 46 to the position inwhich it is shown in Figures 8 and 9. With the frame in this position,therefore, the slide obstructing arm 46 is displaced from the portion 32of the slide and the slide may therefore be advanced to the position inwhich it is shown in Figure 8 if desired, with portion'32 of the slidelocking the camming member 34 against rotation by means of the outsidedoor handle.

Assuming a vehicle to be equipped with locks of the character justdescribed, it will of course be possible for the occupant to lock allthe doors by setting the respective distant control devices into lockingposition. Obviously, however, it would be impossible for such occupanttoI himself open any one of the doors from the inside in order to getout of the vehicle without first releasing the camming member 34 of oneof the locks by operating the distant control device to retract thelatch bolt. After having done this and opened the door, the lockingslide 40 will move to the position in which it is shown in Figures 1 and10, thus preventing setting of the' lever 30 and slide 24 to lockingposition. When the door is closed, therefore, it may be locked from theoutside by means of a key which is provided to effect rotation of cam 31and elevation of slide 36 into locking engagement with cam member 34, ormay be locked from the inside. It may, however, be freely opened fromthe outside unless either locked by means-of a key or by manipulationofthe same by one on the inside.

Several forms of the invention and "whereby the same objectives may beachieved are also illustrated in the drawings. In the form of theinvention shown in Figures 15 and 16 the sliding frame ofthe first formof the invention is dispensed with, the means for blocking slidingmovement of the slide 60, save under the conditions aforesaid,comprising an angular member 6| in the nature of a lever which ispivoted for rocking movement about the axis 62 and is normally held inits uppermost and full line position (Figure 16) by means of a. spring63. The inner end 64 of lever 6l normally lies in the path of theforward projection 60 of slide 60 but, when the wedging and wedgereceiving means are in full` engagement, the wedge receiving means actsto depress the upper end of lever 6| from its full to its dotted lineposition, thus elevating its lower and inner end from the position inwhich it is shown in full lines in Figures 15 and 16 to positions inwhich it is shown in dotted lines in this figure. When in dotted lineposition the lever cannot oppose movement of the slide' 60 toward theleft (Figure 15) and hence engagement of the locking lug 65 of thisslide with the slide actuating or camming member 66. As the action isgenerally similar to the action of the form of the invention firstdescribed, no detailed explanation is necessary.

In the form of the invention shown in Figure 17, the locking lever 10 ispivoted at 1| and normally maintained by a spring 12 in its full lineposition, in which position its inclined inner and edge surface 13 liesclosely adjacent to the correspondingly inclined forward edge surface'I4 of the projection 15 of the slide member 16. When the door isclosed, the lever i9 is depressed by the wedge receiving means, asbefore, and its inner end is lifted upwardly, as indicated in dottedlines in Figure 17, its inner edge surface 13 acting as a cam as itslides along the correspondingly formed end surface 14 and slide 16 thusretracting the slide from its full line toits dotted line position andcausing the lower locking lug 11 of the slide to disengage the slidecamming or operating member 18.

Asimilar result is obtained in the case of the form of the inventionshown in Figure 18, but in this case a frame 80 is mounted for verticalsliding movement, as was the sliding frame 40 inv the case of the formof the invention first described, the arm 8l of the vertically slidingframe, however, has its inner end edge surface 82 inclined and adaptedto slidably engage the correspondingly inclined edge surface 83 of theslide 44 as it moves from its full to its dotted line position, thuscamming the slide 84' to the right (Figure 18) from full to dotted lineposition and formed in two parts; the block 90 being centrally mountedin a vertical slot in the rocking mem ber 9|, and pivotally connectedthereto at 92 so that it may be oscillated in a vertical plane. Rockingmember 9| carries a downwardly projecting tooth 93 at its free end andis normally pressed downwardly by means of a coiled compression spring94. The tooth 93 is adapted to bear down and actuate any one of theseveral levers illustrated in the preceding figures of the drawings. Byreason of 'the mounting of the tooth upon the rocking member 9| thistooth may have a relatively different vertical movement withoutnecessitating simultaneous and equal movement of the jaw 90. Other formsof the invention may be devised to state the circumstances of particularcases, as will be apparent to one skilledin the art.
